The 2017 excavations at the sanctuary-emporium of Gravisca continued the research begun in 2015 to the west of the external strip of the western edge of the Hellenistic sanctuary of Cavatha. The following trenches were opened: LII extension (continuation of trench LII), LIV and LV, the latter both situated west of the archaic temenos of Śuris. The investigations in LII extension exposed the thick macco stone make-up of for a paving of stone slabs (US 5/17; 156/17) belonging to the 6th century B.C. phase (phase III 530/20 B.C.) and probably part of the archaic building dedicated to Cavatha. So far only the northern perimeter of the building has been identified, the robbing of which was documented last season. Two pairs of macco stone blocks (the base of an agalma?) aligned E-W (UUSSMM 4/17 and 157/17) also belong to this building. In trench LII extension it was seen that the thick layer of sand (US 38/16; US 14/17=25/17) was also used in this zone to obliterate the sacred area after the systematic dismantling of the macco stone blocks that constituted the walls of the archaic sanctuary of Carvatha and this relates to the life of the “northern sanctuary” post 420 B.C. A similar sequence was uncovered in trenches LIV and LV (sand UUSS 66/17, 81/17, 148/17), attesting that the same fate was suffered by the sanctuary of Śuris, that was dismantled in the same way. Therefore, the topography for the late 5th century B.C. and throughout the following century can be described thus: across the excavated western sector the perimeters of two buildings are beginning to appear, the northernmost delimited by wall 105/17, which forms a corner with wall 112/17 in trench LV. The second complex is delimited to the north by wall 21/15 and to the east 105/09. These walls, which were restored several times until the end of the 4th century B.C., seemed to enclose two structures that, based on comparisons, can be identified as two ramps (the first excavated in 2003-2004, the second in 2015-2016. The ramps were built at different times and were used to drag the boats that arrived in the port of Gravisca into dry-dock in the two buildings mentioned above, perhaps identifiable as neoria (cf. for example the more complex example of the _neoria at Naxos). To the east of these buildings, in trench LIV, the remains of metalworking activity came to light, traces of furnaces or reddening caused by heat, indicating this was an open area. It is also indicates that all of this northern side, once occupied by the temenos of Śuris, was abandoned and temporarily occupied by artisans working on the reconstruction of the sanctuary.
